Why did i choose this carrer?

Hello everyone. Im going to speak about like as they will suppose why i did choose this carrer (Qhemistry). The truth is since i was child y want to be a atronaut, but when i ended the highschool i really dont have any idea of what i wanted to study. I study anyway for the PSU, not neglecting the hisgchool obviusly and i was selected in the Catholic University in the carrer of Biochemistry. I stayed there almost 2 years (i dont liked the ambient of the university, it was far from my house and i was not very close to the people of my generation, i have my friends but i dont know, anyway i was not comfortable studying there) and after that y worked and prepare me for pay again the PSU . This time i was selected in the University of Chile in the carrer of Qhemistry and Pharmacy, i was expulse because academic problems after the first year and i changed to the carrer of Qhemistry in the same university. Where am i actually and very happy i have to add, im so excited with the carrer, the thruth is that chemistry always i liked in the highschool (i had a brushstroke of chemistry in the eight grade and then in the rest of years i did very well actually in the signature, also thanks to my teacher of chemistry i suppose what it is a really good teacher i fell in love with the chemistry a little because it was a thing that i was good for it and i dont know, i like it). I want to tell and im happy for tell to you it was that chemistry what i saw in the highschool its about nothing of the science itself so im really happy of studiyng chemistry now. Until now i know a few partners of the carrer and they liked to me, they are cool and i have not had many test until now but i have done well until now. When i finish the carrer i want to study a postgrade and after that a PhD in other country of the world i want hopefully, for after back here and be academic of the university. It was i want to do actually when i finish the carrer. I can only study for the tests and achieve a good mark in all courses along the carrer and give my best for be a good chemist.
